This file is the program we are going to run on the Teensy. It tells the Teensy to behave like a PS3 controller. If you are a programmer, feel free to grab the source code and make your own modifications. I also have a hex file that tells the Teensy to treat the SNES gamepad like a USB Keyboard, which is useful for some Android tablets that have USB input, but don't support gamepads.

Now that we have the loader application and the hex file, we need to put the hex file on the Teensy.
